Rozenoord bridge

Limited Installation Height

Rijnstaal and Civiele technieken deBoer were commissioned by the IXAS contractors’ consortium (Fluor, Heijmans, Ballast Nedam) to provide support for the Rozenoord Bridge. The project required an efficient approach as the work had to be carried out under the bridge with limited installation height. To meet this challenge, we utilized the two heaviest truck-mounted cranes in the Netherlands. These cranes allowed us to position the truss girders—each weighing over 60 tons (!)—in the correct locations without disrupting traffic or shipping.

Heavy Truss Girders Made from HD Profiles

One of the key aspects of this project was installing temporary truss structures to bear the bridge’s load and transfer the weight to reinforced support points at the bridge’s sides. For this, we used HD profiles, a specialized type of rolled section not readily available in stock and requiring custom production. Despite these challenges, the project was successfully completed within the tight one-year deadline.

Self-Supporting and Efficient Execution

Thanks to our expertise and experience, we were able to fully design, produce, and install the support structures ourselves. This self-reliant approach ensured maximum control over the entire process, from design and procurement to production and assembly.

The installation of the steel structures over water was particularly noteworthy. To facilitate this, we designed and used pontoon platforms, keeping the waterways open and accessible. Additionally, our rotating telehandler proved invaluable on these pontoons, enabling the efficient erection of the required structures.

This solution allowed the bridge to remain safe without causing any disruption. Our self-supporting approach, in collaboration with Civiele technieken deBoer, provided the client with complete peace of mind. The result: a secure bridge that will remain safe for years to come.
